Jada Pinkett Smith's hospital drama gets a healthy dose of guest stars tonight, with medical-show vet Judy Reyes (Scrubs), Reid Scott (My Boys) and Sarah Lancaster (so solid as an exasperated sibling in Chuck) checking in. As for noble nurse Christina Hawthorne, she cares for a woman who was possibly abused by her boyfriend - but surprising details soon emerge in the case. In other medical cases, Bobbie treats a bigot suffering from abdominal pains, and Ray gears up to assist a biker facing possible paralysis after a motorcycle accident.
* Hell's Kitchen (8/7 CT Fox)
Two weeks. Two trips apiece to the chopping block. Lovely and Tennille have clearly been put on notice. And if the preview of tonight's show is to be believed, things don't look good for the gimpy Dave (broken wrist) or the flummoxed Robert ("I overcommunicated"), either. So keep that in mind while you watch them and the 10 other contestants make sausage (never a pretty sight), then try to feed Drew Lachey, John O'Hurley, Tom Green, Melinda Clarke, Chris "Kid" Reid and Kristy Swanson.
What do Stargate Atlantis and the old Planet of the Apes television series have in common? They paved the way for guest-star roles on Warehouse 13! Actors Joe Flanigan and James Naughton turn up in a tale that has Pete and Myka chasing after a thief who used a Native American artifact to swipe a sculpture.
Everybody needs a best friend - someone to share secrets, go shopping and dodge paparazzi with. The latter is especially true if you're a celebutante of Paris Hilton's stature. The hunt for her special someone comes to an end (for this season, at least) when Paris makes her choice surrounded by Season 2's castoffs. Those who didn't make the cut just might now realize that there are worse things in life.
* Tori & Dean: Home Sweet Hollywood (10/9 CT Oxygen)
Stella! That name is much more than a quotable Marlon Brando bray in the film A Streetcar Named Desire, as we'll see in tonight's Season 4 finale. In this concluding Tori story, Tori and Dean throw a big first birthday bash for daughter Stella Doreen McDermott. It's Stella's party, but Tori might cry if she wants to when the family must bid adieu to an important family figure. Meanwhile, Dean tries to offset a misdeed by giving the family a surprise gift.
